Are their issues with using feeds with embedded videos? When I just ran the feed url through feedvalidator.org (thanks Mixxxture), I get this as an error:
#
line 27, column 0: content:encoded should not contain embed tag (2 occurrences) [help]
<content:encoded><![CDATA[<p><embed type="application/x-shockwave-flash" ...
Yes, the post uses an embedded video but should that be a problem?
